Which symptom is commonly associated with eye strain?

A burning sensation in the eyes is a common symptom of eye strain, which often occurs as a result of prolonged use of screens, reading, or engaging in activities that require significant visual focus. When the eyes are overworked or subjected to factors like harsh lighting or poor posture, they can feel fatigued, leading to discomfort that manifests as burning, dryness, or irritation. This sensation is a signal from the eyes, indicating they need a break, hydration, or a change in viewing habits to alleviate the strain.

Other options do not directly relate to eye strain. Nasal congestion is typically associated with allergies or colds rather than visual fatigue. Loss of appetite generally relates to gastrointestinal issues or stress, while frequent yawning can indicate tiredness or boredom, not specifically eye strain. Thus, the burning sensation in the eyes is clearly linked to the overexertion and discomfort associated with eye strain.
